M ECHANICAL ORGANETTE.

SPECIFICATION forming part of Letters Patent No. 253,855, dated February21, 1882.

Application filed August 22, 1881.

To all whom it may concern:

Be it known that I, PATRICK J. DUGGAN, of Boston, in the county ol'Suffolk and State ot' Massachusetts, haveinvented a certain new anduseful Improved Mechanical Organette, of which the following is aspecification.

The object of my invention is to improve the mechanical construction andthe musical quality and compass of the organette and still retain itscompactness and portability. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure 1 is anelevation of my invention. Fig. 2 is a longitudinal vertical section ofthe same. Fig. 3 is a plan view, parts heilig` removed,so as to showsome of the levers and a part ot' the reed-board, the reeds, and stops.Fig. 4 is a detail showing the method of operating the stops. Fig. 5 isa section showing one complete division of my reed-board with the tworeeds inserted. Fig. 6 is a plan ofthe parts shown in Fig. 5.

In the drawings,A, Figs. l, 2, and 3, represents the outside casing ofthe instrument, of which the part G, Fig. 2, represents the boardandbase which forms the under support for the perforated music-paper,and G' the upper support, between which two supports Gr and G themusic-paper B passes.

C O2, Fig. 2, are the two music-propelling rolls, one or both ot' whichmay be covered by some elastic material, if desirable.

C, Figs. 1 and 3, is a belt-pulley attached to the lower roll, C', anddriven by the belt B2, Figs. 1 and 3, which passes round thedrivingpulley U3, Figs. 1 and 3, attached to the bellows crank-shaft B,Figs. 1, 2, and 3, B being the hand-crank for operating the instrument.

The crank-shaft B, Fig. 3, has upon it two cranks, B3 B4, set at anangle'ot' about thirty degrees the one to the other.

The bellows B7 B2, Fig. 3, are made as shown in Fig. 2-that is, double,the lower part ot' each being stationary, whilethe Lipper part or boardoscillates or tilts on a transverse axis inthe center ot' its length. Toeach of these tilting boards, and immediately over the axis, areattached slotted housings for the purpose of connecting the tiltingboards respectively of the bellows with the cranks B3 B4. These crankswork in the slotted housings B5 B6,

(No inodel.)

Figs. 2 and 3, and cause the tilting boards to oscillate or rock. Thisrocking ot' the upper board will exhaust air from the vacuum-reservoirP, Fig. 2. This reservoir is provided with a spring, S, to assist inmaintaining a vacuum, the rocking motion being produced by the action ofthe cranks B3 B4 on the slotted housings B5 BG, Fig. 3, the bellowsbeing exhaustbellows, and being provided with suitable air passages,andvalves, b b O O, &e., as shown in Fig. 2. l

N N, Figs. 2 and 3, are a series of levers pivoted at N', each beingprovided with a spring, N2, Figs. 2 and 3. The rear end of each lever Nrests on the upper end of a pushpin, N3, Fig. 3, the lower end of whichbears against one ofthe valves, M2, Fig. 2, the valve M2 being supportedby a spring, M3. As the springs N2 and M3 act in opposition to eachother, it is necessary that the spring N2 should exert sufficient forceto overcome the action of the spring M3, and thus allow the valve M2 tobe opened, when the lever N is left free to act, as it will whenever anopening in the paper B is in such a position as to allow the end N4 topass upward beyond the surface of the paper-that is, into the positionrepresented in Fig. 2.

I will now proceed to describe the arrangement of the reed-board and itsadjuncts.

I have shown in Fig. 2 a part, D D D2 D3, of a cylinder which may bebuilt up by uniting thin pieces, or it may be first made solid and thenmortised out by machinery. This grouping of wind-chambers about a commoncenter may embrace any desired part of a circle, or even the whole.

E E E2 E3, Fig. 5, show a sectional view of a wind-chamber complete, thereed-box e c e2 e2 being located in its center, as shown.

F F represent two reeds which are toned for unison or harmony, as may bedesired.

The openings H H', Figs. 2 and 3, extend in a series the whole length ofthe reed-holder. Each series of openings are covered by a singlecontinuous stop. (See K K K2 K2, Figs. 2 and 3.) The stop K isrepresented as open.

A complete division of my system of arrangement consists of the partsshown in Figs. 5 and G-namely, the wind-chamber E E E2 E2, the reed-boxc c e2 e3, and their reeds F F.

IOO

The above complete division constitutes one of a series placed side byside to constitute a longitudinal division which ext-ends the entirelength of the device. (See Fig. 3.) The longitudinal divisions arearranged side by side circumferentially to form the Whole segment ofthereed-board.

I do not confine myself to any limited number of reed-divisions, as Imay use one or more, asrequired.

My method of operating` the stops is illustrated by Fig. 4, inwhich K isone of the stopvalves, and K7 is a swinging cam pivoted at L'. Thisswinging cam K7 is operated by the sliding piece K5 and its pin 7o',thepull-knob being indicated by K6.

Having thus described my invention, what I desire to secure by LettersPatent is- In a mechanical musical instrument, the combination of thesegment reed-board D D' I)2 D3 and the valves M2 with the set ofpushpins N3, levers N, and music-paper, all arranged and operatingtogether, substantially as described, and for the purpose set forth.
